'Edge of the Sword' in the Bible

And the Sabeans fell upon them, and took them away; yea, they have slain the servants with the edge of the sword; and I alone am escaped to tell you.

While he was yet speaking, there came also another, and said, The Chaldeans made out three bands, and fell upon the camels, and have carried them away, yea, and slain the servants with the edge of the sword; and I alone am escaped to tell you.
